HYDRANT.

SPECIFICATION forming part of Letters Patent No. 261,272, dated July 18,1882.

a, Application med Maren 24,1882.' (No model.)

.To all 'whom it mag/,concern Be it known that 1,'JABEz STONE, ofWaterford, in the county of Saratoga and State of New York, haveinvented certain new and useful Improvements in Hydrants, of which thefollowing is a specification.

M v invention relates to the class ofhydrants in 'which a valve is usedwhich closes directly against the current and pressure of the water.

Figure l is a view of the hydrant, partly eX- ternal and partlysectional. Fig. 2 is a sectional view of the upper part of the same.Fig. 3 is sectional View of the valve-chamber, valve, &c., enlarged fromFig. 1. Fig. 4 is a plan of top of valve-chamber castin g, showin g thearrangementofwater-ways used in Figs. l and 3. Figs.

- 5 and 6 are other arrangements of valve-cham ber and water-ways whichcan be used, if pre- 'erred.

A is the stand-pipe or body. B is the valvechamber casting. C is theopening where the water-pipe is connected. D is the valve, with itsouter loose brass cylindrical surface, D', and leather or other suitablebottom surface, E. (Shown in solid black.) F is the valveseat on whichthe valve closes. G is a cylinder of brass fitted into the ironvalve-case Z, and within which D and D slide when moved. H is thevalve-stem, usually rounded at its bottom where it presses against thevalve. I' is the valve-rod, connected with the stem and reaching from itto and through the top of the hydrant, and by it the valve is opened andclosed.

Where the valve-rod passes through the-stuffing-box it is desirable tocover it with brass so, and it is so shown. J is the stufIing-box plate.K is the cover. L is the nozzle. M is the cap to valve-chamber, andthrough it the valvestem passes. -O O are drip-holes,which pass throughthe brass cylinder G and the iron outside of it. P P are waterways eachside of the valve-chamber.

by the raising of the valve no water can escape through them; but whenthe valve is pressed down against the seat these holes O 0 areuncovered, and whatever water is in the standpipe will pass down throughthe holes in the cap M and escape through the drip-holesO O. When thevalve is drawn up into the space just below the cap M the water willfollow the dotted lines with arrow-heads (see Fig. 1) through thewater-ways P P and into the standpipe and discharge through the nozzle..These water-ways can be as shown in Fig. 4; or there can be one largewater-way on one side of the valve; or if the top of the valve-,castin gis made square or circular, as shown in Figs. 5 and 6, the arrangementof water-ways there shown can be used.

To remove the valve for'any purpose, the top K and the stuffing-boxplate J are removed, a long socket-wrench is slipped down over thevalve-rod I, and rests on the brass cap M and over the square nut at thetop of it. This cap M is then unscrewed from the valve-case, and it, thevalve, and valve-rod are all lifted out together. Another set can be putin in place of the pieces removed, or they can be repaired, ifnecessary, and replaced. This facility of removal ofsaid partswithoutremoval of the stand-pipe is one ofthe advantages of the ar`rangement described.

In case the drip-holes become obstructed in any way the end of a rodproperly bent can be passed down through large holes in the cap M andthe obstruction pushed out of the dripholes. The doing this-i. e.,clearing the dripholes without removing the valve from the hydrant-isanother advantage of the arrangement described.

I claim as my invention- The casting B, having the valve-case Z,provided With leak-holes O leading to the outside, and the surroundingwater-ways P, in combination with the perforated cap M and solid valveD, substantially as described.
